Y Serial No.l 83,793.. n' Y' This inventionirelates to hosecouplingsV of the well known type adapted to be oper-l ated by hand forcoupling up the ends oi? flexible hose connections between cars oi a Thepresent invention has particular reference to means for `holding thecoupling gasket` of the hose coupling in place and is in the nature ofan improvem-ent on the construction covered'by my prior pendingapplication, Serial No. 23,999, :tiled April 18, 1925.

In the accompanying drawing; Fig. 1 is a section l,on the line 1-1 ofFig. 2, of a r coupling head embodying my improvement;

Fig. 2 a faceviewof the coupling head; Fig.

3 a detail sectional view of the clamping ring locking means; Fig. 4t aplan view of the clamping ring; Fig. 5 a side view of the clamping ring;and Fig. 6 a sectionV on the line G-Bof Fig. 4.

According to the construction shown in l the drawing, the face of thehose coupling of a circle and having its ends secured to thecouplinghead 1.

head lis bored out so as to receive a. gasket clamping ring 2 which isadapted to engage flexible rubber gasket'9.

The clamping ring 2 is provided with four wedge shaped lips 6 disposedat the periphery of the ring and adapted to engage in an undercutannular groove 3 oi the coupling head. Carried by th-e ring 2 atdiametrizcally opposite points are .tangs 7 and f The tang 7 is providedwith a bore v16 adapted to receive a rod 17 formed as an arc Thecoupling head flange 18 is cut away at four places, down to the bottomoi the groove 3, so that the wedge lips 6 oi .the

ring 2 may be applied tothe coupling head.

When a gasket 9 is tobe applied tothe coupling head, the clamping ring 2is thrown back out of the way, the rod 17 serving to retain the ring inassociation with the coupling head, so that the ring cannot `be mislaid.The gasket 9 having been placed in position, the ring 2 is applied overthe gas- The ring'is then' rotated in a counter-clock#,V

wise direction to the position shown1 in Fig. 2 and in this movement,the lips 6 are caused to engage in the groove, so that the wedge lipsact to clamp the gasket securely in position.

In order to lock the ring 2 in its clamping position, the coupling headis provided with a lug 11 having a bore 12 containing a ball 13 which ispressed 'outwardly by a spring 14. VThe ball13 is adapted to engage a recess 15 provided in the tang 7 when the ring 2 has been turned to itsclamping position, to thereby yieldingly lock the ring in said position.1

Having Jfour uniformly lips v6, the yring 2 acts to apply clampingvpressure more evenly on the gasket and the clamping ring vcannot belost or mislaid, since it is held to the coupling head when not'in itsclamping position, by the rod 17.

spaced wedging Havingnow described my invention, what I claim as newVand desire to secure by Letters APatent; is y 1. The combination with ahose coupling head having a seating :face for a'gask'et, of a gasketmount-eden said face, a rotatable clamping ring for clamping said gasketon said face, an arcuate member carried by Said head,"a tang carried bysaidV ring and having a Vbore extends.

2. The combination with a hose coupling head having aseating face for agasket, of a gasket mounted on said face, a clamping member for clampingsaid gasket on said face, and a rod secured to said head on throughwhich said member which said member is slidably mounted for nlongitudinal movement on said rod, to permit rotative'movement of saidmember on said rod and 'also a swinging movement of said member on saidrod.

In testimony whereof I have hereunto setv my hand. v
